  • Thermal imaging Is the science of seeing heat patterns using special electronic cameras Rather than seeing light, these remarkable instruments create pictures of heat. They measure infrared (IR) energy and convert the data to images corresponding to the temperature.

  • An Infrared System IR Collected IR Energy Windows and Optics IR Sensor S 453C T SP1 470C EMS .85 Electronics Object Environment Detector Electronic Display or Other Output Corporate Presentation Company Confidential 3http://www.fluke.com/fluke/inen/Products/Thermal-Cameras.htm
  • How do we get the picture? Each of the pixels, contain an accurate temperature value. The Imager, through the use of a complex set of algorithms, assign specific colors that correspond exactly with the temperature value found at the specific X Y coordinate. When an image is captured using the Therrmal Imager , all of the background data is also 96 Elements saved along with the picture allowing in-depth analysis using software. 128 Elements Corporate Presentation Company Confidential 4http://www.fluke.com/fluke/inen/Products/Thermal-Cameras.htm
  • Thermal imaging is non-contact applies to most types of equipment and conditions is obtained without disturbing production quickly identifies specific locations allows for detection of problems before failure can scan large areas quickly to identify areas of concern Corporate Presentation Company Confidential 5http://www.fluke.com/fluke/inen/Products/Thermal-Cameras.htm
  • Are Fluke Thermal Imagers easy to use? Yes. If you take pictures with a point and shoot digital camera, you can easily use a Fluke Thermal Imager. Fluke Thermal Imagers can be set either automatic or manual modes, similar to adjustments you might make on a digital camera. Simply: 1. Point 2. Focus 3. Capture As long as you have focused the Imager correctly you basically cannot make any mistakes as you can change Corporate Presentation afterwards with the software everything Company Confidential 6http://www.fluke.com/fluke/inen/Products/Thermal-Cameras.htm
  • Lets put the Fluke Thermal Imagers to work Just a few of the applications Electrical Mechanical / Electromechanical HVAC FACT Fluke Thermal Imaging 7 Corporate Presentation Company Confidential 7http://www.fluke.com/fluke/inen/Products/Thermal-Cameras.htm
  • Electrical Commonly inspected Typical reasons for temperature components hotspots or deviations (3 phase) Power distribution Unbalanced loads Fuse boxes Harmonics (3rd harmonic current in Cables & connections Neutral) Relays/Switches Overloaded systems/excessive current Insulators Loose or corroded connections increased Capacitors resistance in the circuit (typically one side Substations of components heats up) Circuit breakers Insulation failure Controllers Component failure Transformers Wiring mistakes Motors Underspecified components (like fuses) Battery banks would heat up on both side of the fuse Corporate Presentation Company Confidential 8http://www.fluke.com/fluke/inen/Products/Thermal-Cameras.htm
  • Identify a phase unbalance Note the increase in temperature on this phase Corporate Presentation Company Confidential 9http://www.fluke.com/fluke/inen/Products/Thermal-Cameras.htm
  • Identify high resistance connections Corporate Presentation Company Confidential 10http://www.fluke.com/fluke/inen/Products/Thermal-Cameras.htm

  • Tools for measuring loads & harmonics Fluke 330, 350 series Clamp Meters Fluke-345 PQ Clamp Meter 2000A DC 1400A AC Harmonics Power Energy Data Logging Corporate Presentation Company Confidential 12http://www.fluke.com/fluke/inen/Products/Thermal-Cameras.htm
  • Mechanical / Electromechanical Commonly inspected Typical reasons for components temperature hotspots or deviations Motors Pumps Bad cooling- due to reduced airflow Heat exchangers Bearings PQ problems like unbalance, overload or 5th harmonic (voltage) Gearboxes will cause heat dissipation Drive belts Bad alignment Insulation problems with motor windings Bearing problems lubrication, wear, etc.
